PI3EQX10908ZFE

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX10908ZFE is an 8-channel PCIe ReDriver manufactured by Diodes Incorporated, designed for high-performance signal integrity in lossy copper cables and backplanes. It supports serial link rates up to 11.3Gbps and KR backplane applications. The device features per-channel programmable equalization (up to 35.7 dB), transmit de-emphasis (up to 9 dB), output swing (up to 1200 mVp-p), and amplifier gain. It operates on a 3.3V ±10% supply voltage and utilizes a 54-contact TQFN package measuring 11mm x 5mm with a 0.5mm pitch. Configuration is achieved via pin straps, I2C master/slave control, or external EEPROM loading.

• 10Gb fiber channel systems
• 10Gb SFI, XFI, and KR interfaces

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix ZFE against the manufacturer's official datasheet to confirm packaging details and RoHS compliance status. Confirm current availability as distribution channels may list this component as discontinued or end-of-life. Ensure the selected variant matches the required 54-contact TQFN package dimensions and pitch specifications for PCB layout compatibility.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending signals across long lossy copper cables exceeding 10 meters or backplanes longer than 40 inches with multiple connectors. Choose the PI3EQX10908ZFE if the design requires an 8-channel flowthrough pinout architecture. Consider the I2C and EEPROM programming options if software-driven optimization or automated power-up configuration is necessary for the system.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3EQX10 series of PCIe Redrivers from Diodes Incorporated (formerly Pericom). It is specifically engineered to mitigate inter-symbol interference introduced by interconnect mediums. The device serves as a critical interface solution for maintaining signal integrity in high-speed digital environments where standard drivers cannot compensate for significant channel loss.
